ESP-WROOM-32 esptool fatal error
Posted: Wed Aug 09, 2017 9:08 pm
Hello
I'm currently in the process of getting my board up and running. I used a new WROOM module and placed it on my board. My board features an CP2102 Serial converter. I verified a working auto prog circuit (same like on the Espressif Boards) with toggling the pins in Realterm and thus putting the esp32 in download mode or running mode. Works perfect.
I can perfectly read out the mac adress via esptool. But flashing doesn't work. It seems that it has an issue with accessing the flash of the WROOM. But I don't know why. I already changed the WROOM module to another new one, same issue.
